Answer:
lithium oxide is soluble in water
Explanation:
Quite a number of properties varies across a period. Some remains constant whereas others decreases.
As one moves from left to right;
- The energy level remains the same.
- The ionization energy increases progressively as a result of increasing nuclear charge.
- Electron affinity increases from left to right.
- Electronegativity increases.
- Electropositivity decreases.

Assuming that the O2 gas acts like an ideal gas, we find
the following expression to be approximates of the behaviour of this gas:
<span>P V = n R T --->
1</span>
where,
P = pressure exerted by the gas
V = volume occupied
n = number of moles
R = universal gas constant
T = absolute temperature
Further, we assume that the number of moles and the
temperature are constant, hence reducing equation 1 into the form:
<span>P V = k --->
2</span>
where k is a constant. Therefore we can equate two
states:
P1 V1 = P2 V2
Since P1, V1 and V2 are given and we are to look for P2:
25 mL * 2 atm = 100 mL * P2
<span>P2 = 0.5 atm</span>
<span>How does understanding the structure of the atom help you see both unity and diversity in forms of matter?</span><span>
Understanding the structure of the atom helps to understand unity in matter because all matter is made up of those very similar atoms. Understanding the structure of the atom helps to understand diversity in matter because matter can be different (solid, liquid, gas, hard, soft, etc) and knowing the structure of the atom can explain these differences.
Hope This Helps! :3</span>
